SBS2011 DCOM error

We keep getting the following DCOM error on our single sbs2011 server, as follows :-

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{D3DCB472-7261-43CE-924B-0704BD730D5F}
and APPID
{D3DCB472-7261-43CE-924B-0704BD730D5F}
to the user DOLPHIN\sbsadmin SID (S-1-5-21-4227830585-1524740534-106091535-1156) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.

I have been advised to :-

1. Click Start -> Run -> Type -> dcomcnfg, expand Component Services -> Computers -> My Computer -> DCOM Config.
2. Click View -> Detail -> Now you will get Application Name and Application ID in right side.
3. Scroll down and find the application ID {AD65A69D-3831-40D7-9629-9B0B50A93843} -> Right Click -> Properties and select the Security tab.
3. Click Customize under "Launch & Activation Permission" -> click Edit -> Add in the account NT AUTHORITY\SYSTEM and set local launch and local activation.
4. Restart the application Service linked to this Application ID or restart the server and monitor

But when we get to edit the "Launch and Activation Permission" all of the options are greyed out, so we cannot change them.
